TO ALL WHOM IT MAY CONCERN:

Be it ,known that I, CHARLES H. GODFREY, of Stewartsville, in the county of Warren, and State of New Jersey, have invented a new and useful Improvement in Seed-Boxes for Grain-Drills; and I do hereby declare the following to be a full and exact description of the same, suffieient to enable others skilled in the art to which my invention relates to understand and'construct the same, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a plan of the seed-box of a grain-drill, showing my improvement; and

Figure 2 is a transverse sectional view of the same, in the line it" x, fig. 1.

Similar letters of reference indicate corresponding parts in the two figures The nature of my invention consists in providing the shaft over the feed-holes of a seed-box with irregular cams of a peculiar shape, one over each hole, for the purpose of stirring the grain and keeping the feed-holes clear from clogging.

A A, in the drawings, represent the sides of a feed-box of a grain-drill, the bottom B of which is provided with any suitable number of feed-holes, C, over each of which, secured to the stirring-shaft D, is a stirrer or irregular cam. The shaft D has its bearings in the cross-pieces (Z, placed above and over the bottom 13 of the box, and is rotated by a cog-wheel, e, to which motion is given by any suitable means from the running gear of the drill. The stirrers or irregular earns consist of the body ll, of triangular form, thicker in the centre and tapering oii' towards its edges, on which the points or projections e are formed in such a manner that no two of the same shall ever he in line with each other. The outer edge of these points a is made convex in continua tion of the curved edge of the body'E, while the inner edge is made concave. Each point e, in revolving with the cam E onthe shaft D, passes through the feed-hole 0 below the line of the bottom B of the box A, so that any grain clogged in the same is Forced through by the points 2, and as during one revolution of the shaft D and cam E each part of the feed-hole O has been traversed by one of the points 0, no clogging of the holes C is possible, for as soon and whenever the grain. threatens to clog in the hole it is immediately forced through before more can fall on it. Below the bottom B of the box A are the usual slides Z) 6 provided with holes, the slide b being operated by the lever g, pivoted to the outside of the box A, and the slide 6 by means of the setscrew It at the end of box A.

The great advantage of my irregular cams, situated over these feed-holes, in comparison with those devices now in use, is that each of the three points 0 passes through the feed-hole and not merely over it, and that as neither of these points is in line with either of the others, at each revolution of the cam E every part of the feed-hole C is traversed by the three points a.

Having thus described my invention, what I claim as new therein, and'desire to secure by Letters Patent, is The irregular cams e on the stirring-shaft D of a seed-box for grain-drills, substantially as and for the purposes described.

The above specification of my improvement in seed-boxes for grain-drills signed this twentieth day of February, 1867.
